				<p>This tool allows two or more Biblical (currently New Testament) <del><strong>manuscripts</strong> or</del> <strong>manuscript editions</strong> to
				be easily compared in side-by-side and unified views <ins>(no original unedited <abbr title='manuscripts'>MSS</abbr> are yet incorporated)</ins>.
				It demonstrates a fundamental concept in the Open Scriptures framework: semantic linking. All of the contributing manuscripts are
				merged together to produce a single unified manuscript containing every attested variant; additionally, while merging, a manuscript's words are linked
				to their corresponding words in the unified manuscript. (All words in the unified manuscript are normalized by making them lower-case and removing diacritics and punctuation;
				spelling differences and transposed words are not normalized).
				Because each manuscript links back to the unified manuscript, every manuscript is then connected
				to every other manuscript by virtue of their shared links to a common point.</p>
				
				<p>To use, select the manuscripts for comparison and place them in either the (first) <b class='ins'>preferred list</b>
				or the (second) <b class='del'>deprecated list</b>; each list must contain at least one manuscript.
				Reorder the manuscripts in the two lists to indicate precedence so that where
				manuscripts agree, the equivalent content from the manuscript with a higher precedence will be displayed instead of content from a manuscript with lower precedence.
				This matters because manuscripts have differences in casing, diacritics,
				and punctuation. Likewise, the reference system of the manuscript with higher precedence will be displayed.</p>

				<p>In the output, unique content from preferred manuscripts will appear in green as <samp><ins>insertions</ins></samp>,
				whereas unique content from deprecated manuscripts will appear in red as <samp><del>deletions</del></samp>. In the parallel view,
				hovering over words attested to by both preferred and deprecated manuscripts will result in the equivalent
				<samp><ins class='highlight'>insertions</ins></samp> and <samp><del class='highlight'>deletions</del></samp> being highlighted with solid colored borders.</p>

				<p>When more than two manuscripts are being compared, additional formatting is introduced to help identify the additional possible variations.
				<!--Remember that the manuscripts in both of the lists are merged into a single unified manuscript which is then compared with a unified manuscript from
				the merged manuscripts in the other list.-->
				Where multiple manuscripts common to the preferred or deprecated list don't agree <em>among themselves</em>,
				the variant words will appear in <samp class='disagreed'>bold</samp> regardless of whether any manuscripts in the other list also attest to them;
				upon hovering over these words, their attesting manuscripts' names will be <samp class='highlight'>highlighted</samp>. 
				Words identified as potentially being transposed <em>within a manuscript group</em> appear in <samp class='transposed'>italics</samp>, and when hovering over such a word
				the correspondingly transposed word is <samp><span class='transposed transposedHighlight'>highlighted</span></samp> in cyan. However, when
				a word appears to be transposed between the preferred and deprecated manuscripts, then <samp><ins class='translateralTransposed'>insertions</ins></samp>
				and <samp><del class='translateralTransposed'>deletions</del></samp> appear fainter
				than normal; likewise, upon hovering over such a transposed <samp><ins class='translateralTransposed highlight'>insertion</ins></samp> or
				<samp><del class='translateralTransposed highlight'>deletion</del></samp>, they appear with dotted borders to indicate their diminished significance.
				</p>

				<p>By hovering over a word, all of the available morphosyntactic information will be displayed in a raw format.
				In an upcoming edition, this information will be presented in a better interface.</p>
